Tonya Harding is one of the most notorious figures in sporting history, with her he-said/she-said tale of the attack on Nancy Kerrigan taking the spotlight in America (and the world) for much of 1994. Her notorious name has been pulled back into the spotlight this year thanks to Australian treasure Margot Robbie, who both produced and stared in the new award-winning black comedy I, Tonya.

The actress channelled cool girl-bridal style at the I, Tonya premiere in Sydney overnight, wearing a white silk Michael Lo Sordo gown ($2,125; netaporter.com/au) - which is still in stock! She styled her signature blonde lob into a wavy low double-bun, using silver hair accessories to 'knot' the do. Stylish arrivals aside, Margot made quite the impression when we spoke to her about the film live from the red carpet.

We caught up with the actress to find out why she chose to bring the tale to life, and to get her thoughts on the changing nature of Hollywood in 2018.

"It was a brilliant script," she told InStyle Australia, of her decision to produce and star in the film. "It was very rebellious in nature, it was unlike any script I’d read before, so we obviously gravitated towards it because of that. It felt fresh and different but weirdly, and sadly, relevant. That idea of truth and the class divide in America right now and what women are told they’re meant to be and how they’re punished if they speak out against unfairness, so a lot of that felt very relevant but on the surface it was also an amazing script and a lot of fun."

"I’d be laughing at one moment, and immediately feeling weird and guilty that I’d laughed at something, it challenged me as an audience. It’s important to put art out there that challenges people."

"We never expected any of this stuff to happen," she confessed of the success of the film, which today saw the actressnominated for an Oscar. "If it all stops here today, I’ll still be stoked."

As for the current Time's Up movement in Hollywood, Margot was optimistic of the changes to come within the industry.

"I’ve been very fortunate in this industry, but as a woman in the world of course I’ve experienced gender inequality and I think it’s all of our duties to make sure we work towards a society where that doesn’t exist anymore, and it’s going to take a long time, but I think the louder the conversations are, the closer we come to achieving 50/50."
